Quality Indicators
Material and Grade
When you pick small diameter tubing, check the material and grade. Nitinol tubing is special because of its properties. It is made from nickel and titanium. This mix gives nitinol shape memory and superelasticity. These features let nitinol tubing bend and go back to its shape. You want tubing that bends many times without breaking. Fatigue resistance and durability are important for medical and industrial jobs. Nitinol can last through up to 10 million bends. This is much better than other metals.
Look for nitinol that meets top standards. ASTM F2082 and ASTM F2004 are two main standards. These standards show the tubing is safe and strong. The Af temperature range for nitinol is usually 0 to 20°C. This range lets nitinol stay superelastic at body temperature. The right alloy mix and heat treatment control these features.
Aspect | Details |
|---|---|
Typical Af Temperature Range | 0 to 20°C |
Purpose | Superelasticity at body temperature |
Control Factors | Alloy composition, heat treatment |
Standards | ASTM F2082, ASTM F2004 |
Check the grade for reliability. Good nitinol grades have high strain recovery. They have a recovery ratio of about 98%. This means the tubing works well after many uses. High corrosion resistance keeps the tubing safe in harsh places. The titanium oxide layer on nitinol helps protect it. This makes it safe for medical use.
Property | Value | Impact on Reliability and Longevity |
|---|---|---|
Strain Recovery | 5.62% | Makes biomedical devices work well. |
Recovery Ratio | 98% | Lowers risk of breaking under stress. |
Corrosion Resistance | High | Stops damage in tough places. |
Fatigue Resistance | High | Lets tubing handle many bends. |
Fatigue resistance and durability make nitinol a great choice. It works well for small diameter metal tubing in medical tools and other tough jobs.
Note: Biocompatibility is important for neurovascular stents. Nitinol is safe for the body and does not rust. This lowers the risk of swelling or rejection.
Wall Thickness and Size
Wall thickness and size are very important for small diameter tubing. You need tubing with tight tolerances so it works well. If the wall is too thin or thick, it might not fit or could break. Dimensional accuracy is very important for medical devices like stents. It helps the tubing stay strong and flexible.
Tubing Outer Diameter Range (mm) | Wall Thickness Tolerance (mm) |
|---|---|
Up to 0.3 | ±0.010 |
0.3 to 0.5 | ±0.015 |
0.5 to 1.5 | ±0.020 |
1.5 to 2.5 | ±0.030 |
2.5 to 3.5 | ±0.040 |
For 0.2 mm OD, you want a wall thickness tolerance of ±0.010 mm. This tight control helps the tubing last longer and work better. Dimensional inspections check the wall thickness and size. These checks make sure the tubing is even and meets strict needs.
Evidence | Description |
|---|---|
Dimensional precision | Makes tubing work well in important jobs. |
Tight tolerances | Keep tubing even for medical devices. |

Making small diameter tubes needs high accuracy. Both the outer and inner diameters must meet tough standards. This accuracy helps the tubing work well in medical and industrial jobs.
Surface and Consistency
Surface quality is another sign of good small diameter tubing. You want a smooth and even surface. A rough or uneven surface can cause weak spots. These weak spots can make the tubing break or fail. Surface finish types like AO, MP, and CE help you judge the quality.
Surface Finish | Threshold Surface Area (cm²) | Breakdown Potential Characteristics |
|---|---|---|
AO | ~0.5 | More likely to break, normal flaws |
MP | ~5.0 | Flatter flaws, less likely to break |
CE | ~5.0 | Like MP, but flaws are more even |
Special tools can check the surface. These include scanning electron microscopy, atomic force microscopy, and x-ray diffraction. These tools help you find tiny flaws or weak spots. You can also use a simple chemical test with sodium hypochlorite. This test shows if there are inclusions in the nitinol. If the tubing has inclusions, it may corrode or fail.
